Title: Improvements in and relating to colour television apparatus
IPC: H04N9/077
Filed: 1952-04-17
Abstract: 741,929. Colour television. OKOLICSANYI, F. April 13, 1953 [April 17, 1952], No. 9658/52. Class 40 (3). In a colour television transmitter an image 11 is projected on to the sensitive surface 15 of a camera 16 through a filter 12 (Fig. 2), including red, green, and blue strips, R, G and B, together with indexing strips I arranged to produce pulses i in the camera output of greater amplitude than the colour signal pulses r, g, b. The pulses are separated by amplitude filter 17 and applied through amplifier 18 and timing circuit 19 to control pulse generator 20 actuating a blocking circuit 21 connecting the camera output to transmitter 22. The timing circuit introduces a delay corresponding to 1, 2 or 3 signal pulses whereby each indexing pulse causes the blocking circuit to pass either the immediately following red, green or blue pulse whilst suppressing the remainder. The sequence in which colour pulses are passed to the transmitter is determined by a synchronizing signal generator 23 which controls the delay introduced by timing circuit 19 and adds synchronizing information to the transmitted signal. Reference is made to line and frame sequential systems. The transmitter integrates the colour pulses to produce continuous signal trains. The strips in the colour filter are disposed at an angle, preferably a right angle to the line direction of scan. In one arrangement, the indexing strips are light reflecting and non- transparent, and are illuminated from the side facing the camera by lamps 13. The strips may be luminescent. In another arrangement the strips are transparent and illuminated by lamps 13a from the image side. The indexing strips may be narrower than the colour strips, Fig. 3 (not shown), to facilitate the suppression of any indexing pulses breaking through the blocking circuit. Specification 648,257 is referred to. Reference has been directed by the Comptroller to Specification 714,154.

Title: Process for the continous production of high modulus articles from high molecular weight plastics
Inventor: TATE KENNETH R
IPC: B29C48/95
Filed: 1991-10-08
Abstract: A process for producing a high modulus article includes forcing a high molecular weight plastic material, such as polyethylene, through a passage of which the cross-sectional area diminishes in the forward direction of plastic flow, thus producing an extrudate. The plastic material is extruded while it is close to or at its melt temperature, and it is lubricated to obtain substantially plug flow through the passage. The speed at which the plastic material flows through the passage is adjusted so that the elongational velocity gradient at any longitudinal position within the passage does not exceed about 2.6 sec.-1, thus minimizing the degree of molecular orientation in the extrudate. The extrudate can be deformed by drawing while it is maintained at or close to its melt temperature, thus producing an oriented, deformed extrudate. The oriented extrudate is then quickly cooled to preserve the orientation. A suitable plastic material is high molecular weight polyethylene with an average molecular weight lying between about 500,000 and about 1,500,000.

Title: Device for transmitting information with vibrations
Inventor: TSUDA KENJIRO
IPC: H04R25/00
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a device for transmitting information with vibrations with which information can be transmitted while having peculiar meaning more than presence/absence by providing a vibration generating means capable of controlling either frequency or amplitude at least and vibrating the vibration generating means while using secondary analytic data. SOLUTION: Primary audio analytic data (such as a term T of sound existence, maximum amplitude A and maximum frequency F) generated by a computer M are sent to a vibration output device 12. The vibration output device 12 multiplies a prescribed coefficient Ca concerning the maximum amplitude A, multiplies another prescribed coefficient Cf concerning the maximum frequency F and generates secondary audio analytic data (Ca.Al.Cf.'F1.T1) from the primary analytic data (A1, F1 and T1). Then, this frequency information is converted to analog information by a D/A converter and impressed to a pulse generator. Amplitude information is converted to analog information and applied to an amplifier later. When the required information is sent, the pulse generator outputs a pulse at the frequency of Cf.F1. for the term T1. The amplifier amplifies the pulse to the amplitude of Ca.A1. Then, the vibration generator performs vibration with these frequency and amplitude.

Title: Mechanical seal
Inventor: WASHIDA AKIRA
IPC: F16J15/34
Filed: 1982-01-07
Abstract: PURPOSE:To make it possible to obtain a high sealing effect to a mechanical seal without the step of lapping the mating surface of the mechanical seal, by inclining the radial cross-section of one of surfaces continuous to the surface for forming the mating surface, with respect to the axial line. CONSTITUTION:A seal ring 12 and a packing are simultaneously baked and joined together upon the molding of the packing. Further, the seal ring 12 is made of a fluorine contained resin charged with a filler, such as, for example,  polytetrafluoroethylene. Further, the seal ring 12 soon conforms to a surface 6  without the seal ring being lapped since a mating surfaces S has a very narrow  radial width, so that high sealing effect exhibits. Further, frictional power may  be less since the seal ring 12 has a very low frictional coefficient, and therefore,  the amount of generated heat may be less.
